Reset Operation - White Rodgers NP100 Installation Instructions & User Manual

Reset Operation

If a voltage spike or static discharge blanks out the display or
causes erratic thermostat operation, you can reset the thermostat.
Move SYSTEM switch to OFF, then press both
simultaneously, and then move SYSTEM switch to HEAT while still
pressing buttons. This reset will restore your thermostat's initial
factory setting.
Remember to turn off your heating / cooling
system BEFORE resetting your thermostat. You will then have to
go through a full initial setup described in Part 3 and Part 4 of the
manual before you can turn your Heating & Cooling system back on.
Failure to follow this instruction may lead to your Heating & Cooling
system damage or malfunction.
